The building is designed to evoke the image of Ryūgū-jō, or Dragon Palace, the underwater dwelling in the Urashima Taro fable.
The Tamatebako appears in the story "Urashima Taro", where the fisherman was invited to the enchanted palace of Otohime, who is the Mistress of the Sea, after saving a turtle.
